Fixed Inductors Procurement Notes

Verify RoHS compliance status as sources indicate variations between leaded and unleaded terminations for this series. Confirm exact tolerance suffix requirements, as 'F' typically denotes ±1% while other suffixes may vary. Ensure the selected variant matches the required DC current rating of 475 mA for the specific application load conditions.

Fixed Inductors Selection Notes

Select this component for applications requiring precise low-nanohenry inductance in a minimal footprint. The unshielded nature requires careful PCB layout to manage potential electromagnetic interference coupling. Verify that the 475 mA current rating exceeds the peak operational current to prevent saturation or excessive heating.
